Pond Aquaclear, Blanketweed & Algae Control, Blue Dye For Pond Water/Water Features, Stops The Growth of Green Algae and Blanket Weed, Filters Out UV Light (1 litre)

Administer the required amount then sit back and wait a few weeks, it does work and also makes the water a pleasant light blue, make sure you have gloves on a be careful of splashes it will stain quite badly, the plants and wild life have thrived with this added to the water, a little expensive but it does work!!

This product does seem to have helped with a blanket weed issue since adding have had no weed appear, beforehand I was having to manually remove the blanket weed on a daily basis.

It does work in the deeper areas of the pond by restricting the UV light but you really need to shade the pond and make sure no other issues are causing problems

The key to using this additive, which is basically a harmless dye, is to add it to the water before the weather gets to the point where the blanket weed starts growing. It works by restricting the spectrum of the light that passes into the water. This year the water has remained very clear and the fish seem quite happy (and I can see them!). Last year I added it late, and while it slowed down the growth of the weed, it was not as effective.

We gave our pond a complete clean before applying this but it does seem to be reducing the amount of blanket weed that has grown since. Even more important, it greatly improves the appearance of the pond by dyeing the water blue.

I have used this product for many years - it works for me - would recommend

Ok

It works well
